In a surprise update made by the official Japanese card website, two new Plasma Gale cards have been revealed. Cubchoo and Beartic, numbered 21 and 22 out of 70, respectively, are both Water-type. These two cards will join Pokémon such as Lugia-EX, Rotom, Donphan and Crobat when Plasma Gale is released September 14th, later this year. Translations for Beartic and Cubchoo can be seen below.

The official site has also shown that non Plasma Pokémon, like the Cubchoo below, can evolve into Plasma Pokémon, like the Beartic below.
